It says get 5 super kills. I've gotten 3 3 2 in my last 3 games and it shows me at 2/5. Only 40%. Obviously bugged Edit:Very bugged. I got 2 or 3 super skills with my sentinel shield super several times after this post to no avail. Eventually I figured out only THROWING YOUR SHIELD counts. Sure enough after I figured this out i got it. That being said this is a huge bug bungie needs to fix. That was insanely frustrating.
